Your wheel base is only a little longer than mine was.
Some tucked up rocker protection, that runs to the rear wheels(nice for a step to access the bed), and you SHOULD be okay, though, I dont know what the trails you have in mind look like.
My buddy had one like yours, but on 37s, full length rocker protection, and good bumpers, ARBs front and rear, hydraulic winch in front, and an electric in the rear. That would go ANYWHERE.
I wouldnt worry too much. With some patience, and skill, I have seen subarus and VW bugs go places that wouldnt even imagine. Just need to remember when wheeling a full size with a diesel... these things require a different approach in many different conditions, due to them being very heavy in the front end....
OH, and a set of Warn hubs.... my vacuum hubs were the first things I broke...though, that was a 4wd launch on dry pavement...hehe
As far as the radius arm, and coil conversion... more money and effort than its worth in my humble opinion. I prefer the simplicity of the leaf spring front, even if you do lose a little turning radius.. but, its not as much as you would think...
BTW, which set of tunes/chip you running?
